Text mode files are required to use a single delimiter to show where lines end, that's why it's called the "line ending".

Atom is smart enough to be able to read files that have multiple different line endings within them, and will only touch them on lines you edit, but changing the line ending using the selector changes it for all lines in the file. That is exactly what you are asking it to do after all 😉.

If you need to insert multiple different line endings in a document you'll need to open it in something that edits the file as binary data since you are explicitly not treating it as a text mode document.
